Internal Curing with Crushed Returned Concrete Aggregates
High performance concrete (HPC) requires a low water-to-cementitious materials mass ratio (w/cm), often with the inclusion of supplemental cementitious materials such as silica fume in the mixture, thus necessitating the use of a superplasticizer. Because of the low w/cm and rapid reaction at early ages, proper curing from the earliest time possible is very essential in HPC. Internal curing has...
متن کاملResidual Mechanical Properties of Concrete Made with Crushed Clay Bricks and Roof Tiles Aggregate after Exposure to High Temperatures
This paper presents the residual mechanical properties of concrete made with crushed bricks and clay roof tile aggregates after exposure to high temperatures. One referent mixture and eight mixtures with different percentages of replacement of natural aggregate by crushed bricks and roof tiles are experimentally tested. The properties of the concrete were measured before and after exposure to 2...
متن کاملResidual Compressive Strength of Recycled Brick Aggregate Concrete at High Temperatures
-Utilization of construction debris as recycled aggregates in the production of concrete is gaining momentum nowadays due to the availability of large quantity of demolition waste. The recycled brick aggregate (RBA) concrete is made used for the production of low grade recycled aggregate suitable for concrete production. The risk of concrete structures exposed to fire is also on the increase du...
متن کاملUtilization of sludge as brick materials
Bricks manufactured from dried sludge collected from an industrial wastewater treatment plant were investigated. Results of tests indicated that the sludge proportion and the firing temperature were the two key factors determining the brick quality. Increasing the sludge content results in a decrease of brick shrinkage, water absorption, and compressive strength. Results also showed that the br...
متن کاملMechanisms of Phosphorus Removal by Recycled Crushed Concrete
Due to urbanisation, there are large amounts of waste concrete, particularly in rapidly industrialising countries. Currently, demolished concrete is mainly recycled as aggregate for reconstruction. This study has shown that larger sizes (2-5 mm) of recycled concrete aggregate (RCA) removed more than 90% of P from effluent when at pH 5. Analysis of the data, using equilibrium models, indicated a...
